Microservices Vs Monolithic Architecture

If something goes wrong in a microservice-based application, users can usually spot it. The monolithic approach is a traditional way to create an application as a single and autonomous unit. We can compare it to a single indivisible block, which means the functions are managed in one location. And that, in turn, means that the code base is exposed to excessive space that is impossible to split into separate blocks. And here, it is worth mentioning the uniform layer of monolith consisting of a database, client-side user interface, and server-side application that are interconnected and dependable.

monolithic vs microservices pros and cons

Responsibility for a specific, well-defined microservice results in a gentler learning curve for new hires, who can be productive much sooner. The only way to scale a monolith is to replicate the entire application, which isn’t always efficient. Microservices allow for quick, independent service delivery. Monolithic architecture is a single, extensive, executable application.

The Disadvantages Of Monolithic Architecture

The main benefit of monolithic applications is that they’re usually easier to work with since you’ll have fewer variables to worry about. However, since the applications will be larger and more complicated, it will also be harder to make any changes further down the line. For any new developer joining the project, it is very difficult to understand the logic of a large Monolithic application even if his responsibility is related to a single functionality. I’d risk the statement that a successful migration towards microservices architecture depends more on the proper organization structure than any other factor.

Bigger web applications become more complex and consequences in reduced code readability, difficulty in development and debugging. A microservices architecture is distributed with more moving parts than a monolith. To scale a microservices-based application, you only need to scale certain components, which optimizes resource usage. It is very easy for a new developer to onboard the project as he needs to understand only a particular microservice providing the functionality he will be working on and not the whole system.

monolithic vs microservices pros and cons

Here, the monolithic architecture that all developers are familiar with and that has a faster deployment time will be more appropriate. The term monolith comes from an ancient representation of a huge rock. When we talk about software, monoliths are nothing but a large block of codes having multiple modules. The application and the business logic is encapsulated in a single deployable binary called a monolith. Usually, a monolith consists of a conventional three-tier architecture, namely, a database, a user interface, and a server-side application. The below diagram represents the idea of the monolithic in a nutshell.

Dynatrace’s PurePath makes it easier to monitor microservices. Its out-of-the-box distributed tracing and code-level insights provide end-to-end visibility across complex application environments. As your company grows, your applications and services become more complex.

What Is Important While Choosing Between Monolith And Microservices?

With them, you can scale applications at will and not think about costly makeovers for the entire product. They also offer lower operating costs at scale and high reliability. First you need infrastructure and investment in DevOps’ work to make it happen. For microservices architecture, you have to adhere to a full-fledged all-around approach following Agile methodology. The team should be mature enough and efficient to manage separate microservice components.

Team members may also handle just one facet of development, rather than overseeing and entire service, which can lead to blind spots. The distributed nature of a microservice application means that your teams will also be distributed. Teams should take ownership over specific services and are expected to handle all aspects of programming, deploying, and maintaining their services. Even though teams operate independently of one another, just like services have to communicate with one another, communication between these teams is highly important. Leaders will need to make a concerted effort to encourage collaboration between teams to make sure standards are being met. Microservices architecture isn’t just limited to coding, it requires well-planned deployment on cloud platform too.

  • You may have to refactor your code to achieve this level of decoupling.
  • You can also measure response times on webspace endpoints and generate logs.
  • It is not always easy to tell where microservices reside, which can make securing them a pain.
  • If no data shows up on the stock of goods, fix the warehouse.
  • Monolithic architecture is considered the traditional style of software development.
  • However, since the applications will be larger and more complicated, it will also be harder to make any changes further down the line.

When you set out to create something, the first thing you’re going to need is a plan, as that will help guide you through the process and ensure that you stay on track. This is true for physical products as well as software and services. Each microservice can use different technology based on the business requirements. The development velocity is poor at best and granular scaling is out of the question. Additionally, if something breaks, chances are the entire app goes down.

Advantages Of Monolithic Architecture

Monoliths also have a distinct set of benefits that should be considered while deciding the optimal architecture for your application. Let’s talk about Microservices vs Monoliths pros and cons. The image above shows a distributed architecture, which is enabled by the implementation of microservices. The diagram indicates that small microservices can be deployed on a heterogeneous set of hosts. The hosts can range from Bare Metal instance to public cloud.

monolithic vs microservices pros and cons

Independent units can scale horizontally or vertically, depending on your needs. Scaling isn’t limited by the capacity of each service and can be completely automated. You can isolate services that require a greater workload and scale them independently of the rest of the app. As the code base is small, you can focus on one particular module and fully understand it. Additionally, the release of one unit isn’t limited by the release and maintains smaller services than one large one. Module dependencies make the app’s architecture more complex and hard to understand, especially for new developers who join the team.

That is exactly why both approaches coexist beautifully – each of them occupies its own niche. Let’s find out when you should choose monolithic architecture or microservices and why. Nevertheless, it all depends on a number of additional parameters.

In addition, services can be written using different technologies. All this complicates the process of testing the application. Complicated testing.Of course, a more complex system consisting of disparate services created using different tech stacks requires a more thorough approach to testing.

They decided to consolidate all of the services into a monorepo and merge the queues for each destination into a single service. For this organization, it made more sense to collect all of these destinations, rather than deploy over 100 individual services for a single change to a shared library. This dramatically increased the team’s velocity, freeing developers up to make proactive improvements. There’s a lot of buzz about microservices, and for good reason, but the complexity of this approach requires greater coordination across your team and comes with a few disadvantages. We already mentioned that the architecture of microservices is divided into several components. Each service has its own purpose and also its own database relevant to its functionality.

Pros And Cons Of A Monolithic Approach

Horizontal scaling of microservices enables alterations only for a particular function. Moreover, involving more team members does not affect the workload since each team member works on separate services. Being a conventional approach, monolith architecture is mature enough for developers who are not required to possess specific skills as with microservices. Since all functions are unified, it is easier to manage them in one centralized directory. There is a misconception that businesses have to switch to microservices when they want to profoundly implicate the enterprise as in the case of Netflix, Google, or Spotify.

monolithic vs microservices pros and cons

It is a good idea to use this solution to interact with API Gateway or different microservices. Projects on which telecommunication, television networks, Ridesharing apps, food delivery apps and gigantic eCommerce platforms run are usually based on Microservice Architecture. As your application grows, you’ll develop dozens, https://globalcloudteam.com/ if not hundreds, of services. Managing this many services and their dependencies can be overwhelming without the right tools. You need dedicated devops teams that can handle all aspects of a service, from programming to deployment. Every service in Microservice architecture-based web applications uses a different database.

Microservices Vs Monoliths: Architectures

And at the same time, when the adoption of microservices proliferates, there are assumptions that microservices are not to the rescue. Monolith can be easier to develop, and if you do not need advanced scalability, it may be your win-win solution. We are here to debunk myths and some opinions and help you differentiate them by giving you a brief guideline of pros and cons. Monolithic architecture runs on a single application layer that joins all architecture functionalities. This architecture doesn’t involve as many actors as other architectural styles.

By starting with microservices, you have to consider hiring several software development teams from the very beginning, focusing on each service . But to deliver a holistic outcome, they still have to be involved in the intercommunication. For complex projects with a variety of components, features, and modules, it’s better to go for a microservice-based architecture. For example, with monolithic single-based architecture and components hosted in one directory, the delivery is streamlined. For microservices, testing is a weak area since if there are too many points of failure, the whole system needs to be scanned from scratch.

Monolithic Architecture: Whats It All About?

Components in a monolith typically share memory which is faster than service-to-service communications using IPC or other mechanisms. Steve Jones, MDM at Capgemini once said, “Microservices is SOA, for those who know what SOA is”. So, those who know about SOA, most think that they are the same, or the difference is not much clearer in their mind. We can’t blame them also, if we talk about a cake and a pastry, we will find more similarities than differences. So let’s try to understand the differences between the two.

Changes to the technology stack are expensive, both in terms of the time and cost involved. With a single codebase, monolithic apps can easily handle cross-cutting concerns, such as logging, configuration management and performance monitoring. Monolithic architectures are simple to build, test and deploy.

The monolithic architecture also makes an application easier to test out and deploy since it will all be packaged as one. However, testing can often be simpler with a microservices application because it’s easier to see how a change impacts the rest of the program. Each functionality can be written in a different language Monolithic vs microservices architectures and has dedicated solutions, specified for the function alone. If something breaks, it’s the single microservice that suffers and goes out of order. A monolithic application’s structure is often referred to as a spaghetti code. This means that it has a large complexity and puts additional pressure on developers.
